While Indy was playing the Jets, released Colts running back told ex-teammate to 'man up' on Twitter

Two weeks ago, when the Indianapolis Colts cut running back Chris Rainey, head coach Chuck Pagano dodged questions about why, saying only its was "an in-house deal.”

"That's all I'll say about it," Pagano added.

But not all Rainey would say about it.

Turns out, it probably was for some training-camp horseplay. Rainey ripped teammate Daniel “Boom” Herron on Twitter after the running back caught a 12-yard touchdown pass in the second quarter Thursday night game against the Jets.

Rainey quickly deleted the tweets, but we have screen captures.

According to USA TODAY Sports' For The Win, Rainey then engaged in a Twitter spat with other users and quickly deleted those exchanges, "ending in him making comments about their mothers."

This isn't the first time Rainer has been in trouble or the first time a team has had enough of his antics. In 2010, he was arrested for stalking his ex-girlfriend and was cut by the Pittsburgh Steelers in January 2013 after an arrest for simple battery.
